Message #2 Posted by Eric Smith on 3 Oct 2006, 6:20 p.m., in response to message #1 by Daniel Alvarez To take apart a clamshell (18C, 19B, 19BII, or 28S), you have to peel off labels and drill out a bunch of heat stakes. Once you swap parts, you can glue it back together, but it may not be as "solid" as the original. I was using an older 28S with a broken battery door in school last spring, because I didn't want to risk losing my good one. I taped the battery door to the calculator. Not pretty, but it worked.

It doesn't close like this, but the 28s is actually a desktop calculator if I ever saw one.

Re: 19b II Housing Change Possible ? Message #5 Posted by Ron on 4 Oct 2006, 12:42 p.m., in response to message #1 by Daniel Alvarez I took a badly damaged 19BII apart in boring a meeting once. It had several broken heat stakes. With all those stakes, it definitely was not made to be reassembled. On this particular calc, the stakes were broken about half way down, so I couldn't just reheat or reglue the heads. If you're careful, I suppose you could drill them out and glue as someone suggested - What kind of glue would work on this plastic?
